Detailed Description
The technical solution of the present invention is further described below with reference to the accompanying drawings and examples.
Example 1:
the embodiment provides a rubbish compression transfer station sewage treatment system, and this system includes following device: the device comprises a first sedimentation tank 1, a buffer tank 2, a rough filtration tank 3, a sewage reactor 4, a second sedimentation tank 5 and a reuse water tank 6.
The sewage generated by the domestic garbage compression station passes through the first sedimentation tank 1 to remove large sundries and precipitable impurities, and then enters the buffer tank for temporary storage. The sewage treatment system has a high load operation mode and a low load operation mode. The existing sedimentation tank (namely the first sedimentation tank 1) of the garbage compression station is used for settling precipitable and floating impurities in sewage, and a specially-assigned person is equipped to regularly clear the impurities in the sedimentation tank. The garbage compression station usually has the following operation time: 6: 00-14: 00, the compression operation of one whole day can be completed in 8 hours, a large amount of compressed sewage can be generated in a short time, and basically no sewage is generated in other time periods. The buffer pool 2 can store sewage generated by the garbage compression transfer station for 3 days, is used for buffering a large amount of garbage filter press liquid generated in a short time and balancing pollutant concentrations (COD, NH3-N and the like) of sewage of different sources (different types of garbage filter press liquid and vehicle/road surface flushing sewage), so that the relatively stable water inflow and pollutant load are achieved, and the phenomenon that a sewage supply system is subjected to overlarge impact is avoided. The sewage reactor preferably adopts an MBBR reactor 4, the reactor adopts an immobilized biomembrane, and sludge circulation and water circulation separation can better adapt to the treatment scene of frequent sewage pollutant load and water quantity change.
1) High load mode: the sewage treatment of the high-load mode domestic garbage compression transfer station aims at the sewage reaching the nano-pipe standard. Sewage in the buffer tank enters a coarse filtration tank 3 to remove insoluble impurities in the sewage at 70-130% of the normal flow of the system design, then enters an MBBR reactor 4 to carry out biochemical treatment, and the treated sewage enters a second sedimentation tank 5 to remove sludge in the sewage and is finally discharged, such as a municipal sewage system.
2) And (3) low-load mode: the sewage treatment of the low-load mode domestic garbage compression transfer station aims at sewage recycling. Buffering, the sewage in the step 2 enters a coarse filtration tank 3 to remove insoluble impurities in the sewage by 20% -70% of the normal flow of the system design, then enters an MBBR reactor to carry out biochemical treatment, the treated sewage enters a second sedimentation tank 5 to remove sludge in the sewage, and the obtained clear liquid enters a reuse water tank 6 to be used as reclaimed water. Preferably, a sterilization device is also provided in the reuse water tank 6.
And when the domestic garbage compression station is in a normal operation period and the residual untreated capacity of the sewage treatment system is 150-200% larger than the demand of the reuse water, the sewage treatment system operates in a high-load mode. When the domestic garbage compression station operates at a low load or stops operating at a time interval and the residual untreated capacity of the sewage treatment system is 150-200% less than the demand of the reuse water, the sewage treatment system operates at a low load
In one embodiment, the MBBR reactor 4 is a fluidized bed reactor. Can better adapt to the characteristic of large COD concentration of sewage in a compression station, quickly realize dynamic balance of a biological membrane and realize automatic membrane removal, and can effectively reduce the sludge production.
In one embodiment, the sludge and impurities generated in the buffer tank 2, the coarse filter tank 3, the sewage reactor 4, the second sedimentation tank 5 and the reuse water tank 6 are discharged into the first sedimentation tank 1 at regular time. The accumulated insoluble impurities in the first precipitation tank 1 are cleaned at regular time and sent to a garbage compression device for compression and dehydration. Preferably, the insoluble impurities can be compressed and dehydrated together with the household garbage after being mixed. The sewage of the compression station has higher COD, and the sludge yield is far higher than the sludge yield of the domestic sewage, namely about 100t DS/ten thousand m 3. But the total amount of sewage is less, and the yield of sludge is not high. Taking the most common garbage compression transfer station with the compression scale of 100t/d in Guangzhou as an example, the total amount of sewage generated in each day is about 5 tons, and the amount of sludge generated in sewage treatment is about 250kg (based on 80% water content), and constructing separate sludge dewatering, storing and transporting equipment causes more resource and investment waste. The most economical and reasonable treatment mode is to carry out sludge dehydration by adopting the existing garbage compression equipment of the garbage compression transfer station and convey the sludge and the garbage to a household garbage terminal treatment facility.
When the concentration of the sewage pollutants generated by the household garbage compression station is greater than the designed value of 150%, the household garbage compression transfer station wastewater treatment system can operate in a high-load mode all day. The domestic waste compression transfer station is because the change of weather and compression treatment's rubbish kind, and the sewage COD concentration that the rubbish compression produced can appear by a wide margin change, and its daily average concentration can appear 2 ~ 3 times changes occasionally, and sewage treatment implements through the operation of priority high load mode and ensures the discharge to reach standard of sewage when the concentration of intaking is too high.
The above table shows the water quality condition of the sewage of a certain garbage compression transfer station treated by the system. Pollutants TCOD in the sewage of the garbage compression transfer station is 6640-8100 mg/L, NH3-N is changed between 78-97 mg/L, and after the system is processed by the system, the water quality of the sewage outlet water can stably reach the requirements of the water quality of the sewage discharged into a town sewer specified by GB T31962 2015 in a high load mode; under the low-load treatment mode, the quality of the effluent can stably meet the requirement of the water quality of the flushing water for roads and vehicles specified in the recycling of the urban sewage of GBT 18920-2020.
Example 2:
reference example 1 was made, with the difference that: the MBBR reactor 4 is a fixed bed reactor. Can better adapt to the characteristic of large COD concentration of the sewage of the compression station and can effectively reduce the sludge production. The reactor fixed film assembly needs to be stripped periodically when the resistance in the reactor is increased.
The above embodiments are only for illustrating the technical idea and features of the present invention, and the purpose of the present invention is to enable those skilled in the art to understand the content of the present invention and implement the present invention, and not to limit the protection scope of the present invention by this. All equivalent changes or modifications made in accordance with the spirit of the present disclosure are intended to be covered by the scope of the present disclosure.
